IPP Authentication is a feature which provides 'HTTP Basic Authentication' for IPP Print-Jobs. Use this OID to Enable/Disable IPP Authentication. 0 - Disable IPP Authentication 1 - Enable IPP Authentication npSecurityIppAuthentication(1.3.6.1.4.1.11.2.4.3.20.61.0) is dependent on npSecurityIppAuthUsername(1.3.6.1.4.1.11.2.4.3.20.62.0) and npSecurityIppEncryptedAuthPassword(1.3.6.1.4.1.11.2.4.3.20.63.0). To enable npSecurityIppAuthentication, npSecurityIppAuthUsername and npSecurityIppEncryptedAuthPassword have to be first configured with valid values. Once enabled, npSecurityIppAuthentication can independently be disabled. npSecurityIppAuthUsername and npSecurityIppEncryptedAuthPassword will continue to retain their values. Errors returned: BAD VALUE(v1) or WRONG VALUE(v2/v3) will be returned when the OID is set with invalid value. GENERIC ERROR will be returned if the interdependency validation between the above three OIDs fails.
